CROSS REFERENCE TO RELATED APPLICATIONS

This application claims the benefit of U.S. Provisional Application No. 60/811,580, filed Jun. 7, 2006, which is hereby incorporated by reference.

FIELD OF THE INVENTION

In general, embodiments of the present disclosure relate to disposable wearable absorbent articles. In particular, embodiments of the present disclosure relate to disposable wearable absorbent articles with anchoring systems.

BACKGROUND OF THE INVENTION

Disposable wearable absorbent articles include disposable diapers and disposable incontinence undergarments. A disposable wearable absorbent article can receive and contain bodily waste while being worn by a wearer. Such articles can be made with various materials in a number of configurations. For example, a disposable wearable absorbent article can be made with a stretchable waistband and a non-stretchable outer cover. The design of a disposable wearable absorbent article can affect the way that the article fits on a wearer. Unfortunately, some disposable wearable absorbent articles fit wearers poorly.

As an example, some disposable wearable absorbent articles with stretchable waistbands and non-stretchable outers cover can have a bulky form on a wearer. A disposable wearable absorbent article that has a bulky form can feel uncomfortable and look unattractive. Also as an example, some disposable wearable absorbent articles with stretchable waistbands and non-stretchable outer covers can resist conforming to a wearer's body as the wearer moves. A disposable wearable absorbent article that resists conforming to a wearer's body can feel uncomfortable and look unattractive. As a further example, some disposable wearable absorbent articles with a stretchable waistband and a non-stretchable outer cover can sag or slip down on a wearer. A disposable wearable absorbent article that sags or slips down on a wearer can feel uncomfortable, look unattractive, and perform poorly as the article tends to leak.

DETAILED DESCRIPTION OF THE INVENTION

Embodiments of the present disclosure include disposable wearable absorbent articles with anchoring systems that fit wearers well. In some embodiments, these articles can include stretchable outer covers. The designs of these disposable wearable absorbent articles allow the articles to have an underwear-like appearance that conforms to a wearer's body as the wearer moves. The designs of these articles also help prevent the articles from sagging or slipping down on a wearer. As a result, the disposable wearable absorbent articles of the present disclosure can feel comfortable, look attractive, and perform well as the articles tend to fit snugly, stay in place, and not leak.

Embodiments of the present disclosure include disposable wearable absorbent articles. Throughout the present disclosure, the term “disposable wearable absorbent article” refers to an article, configured to be worn on a lower torso of a human body of a wearer, configured to receive and contain bodily exudates (e.g., urine and feces) from the body, and configured to be disposed of after a single use by the wearer. Thus, a disposable wearable absorbent article is configured such that the soiled article, or a soiled portion of the article, is not intended to be restored and reused (e.g., not intended to be laundered). Examples of disposable wearable absorbent articles include disposable diapers, disposable incontinence undergarments, etc. A disposable wearable absorbent article can be configured in various ways, such a pant-type configuration with a pre-formed waist opening and leg openings and a fastenable configuration with means for a consumer to fasten the article around a body of a wearer.

In embodiments of the present disclosure, a disposable wearable absorbent article can include an absorbent core. Throughout the present disclosure, the term “absorbent core” refers to a part of a disposable wearable absorbent article configured to absorb bodily exudates received into the article from a body of a wearer. An absorbent core can be configured in various ways, as will be understood by one of ordinary skill in the art. Examples of absorbent cores include absorbent core assemblies (with one or more optional core structures), bucket-shaped absorbent cores, removable and/or replaceable absorbent cores, etc.

In embodiments of the present disclosure, a disposable wearable absorbent article with an anchoring system, as described herein, can include a stretchable outer cover. For example, the outer cover can be a uniaxially stretchable outer cover, configured to stretch in one direction. Also as an example, the outer cover can be a biaxially stretchable outer cover, configured to stretch in two directions. In various embodiments, the outer cover can be configured as described in US non-provisional patent application entitled “Biaxially Stretchable Outer Cover for an Absorbent Article,” filed on Nov. 15, 2006 with Express Mail No. EV916939625 and further identified by attorney docket number 10643, which is hereby incorporated by reference.

In embodiments of the present disclosure, a disposable wearable absorbent article with an anchoring system, as described herein, can include an outer cover configured in various ways, including configurations of part or all of the outer cover as stretchable, non-stretchable, with an elastic nonwoven, with an elastic film and extensible nonwoven, with an extensible film and an elastic nonwoven, pre-stretched with elastic strands allowed to contract, mechanically activated, with zero strain laminate, and/or combinations of these and any other outer cover configurations. In various embodiments of the present disclosure, a disposable wearable absorbent article with an anchoring system, as described herein, can include a printed outer cover forming one or more elements of an anchoring system separately or in combination with various basis weights, chemistries, and/or mechanical activations, as will be understood by one of ordinary skill in the art.

In embodiments of the present disclosure, a disposable wearable absorbent article with an anchoring system, as described herein, can be configured with various structures and/or functions as described in US non-provisional patent application entitled “Absorbent Article Having an Anchored Core Assembly,” filed on Nov. 15, 2006 with Express Mail No. EV916939634 and further identified by attorney docket number 10432MQ, which is hereby incorporated by reference. Also, in embodiments of the present disclosure, a disposable wearable absorbent article with an anchoring system, as described herein, can have a wrap and tuck configuration as described in US non-provisional patent application entitled “Disposable Absorbent Article Having a Wrap and Tuck Configuration,” filed on Nov. 15, 2006 with Express Mail No. EV916939617 and further identified by attorney docket number 10644, which is hereby incorporated by reference.

Throughout the present disclosure, various figures illustrate human bodies. As a whole, these figures are intended to illustrate the presence of various external human anatomical features and general relationships between these features. For ease of reference, the present disclosure refers to many of these features using simple and informal terminology. These human anatomical features can relate to disposable wearable absorbent articles with anchoring systems, according to embodiments of the present disclosure. Some figures are intended to illustrate how such articles can fit on human bodies.

In the present disclosure, figures that illustrate human bodies are not intended to illustrate all human anatomical features. These figures are also not intended to teach precise details or exact proportions of the human anatomical features that are illustrated. Further, these figures are not intended to limit embodiments of the present disclosure to any particular size, shape, or type of human body.

When a disposable wearable absorbent article is placed on a wearer, the article is placed in an initial position with respect to the wearer. The location of this initial position can depend on a number of factors, such as the size of the article, the shape of the wearer's body, and the manner in which the article is placed on the wearer. For example, an initial position of a fastenable diaper can depend in part on a location at which the diaper is fastened around a wearer. However, as a disposable wearable absorbent article is worn by a wearer, a number of forces can act upon the article.

Some of these forces can tend to move the article on the wearer. Throughout the present disclosure, the term “load” refers to a force that tends to move an article out of place on a wearer. First, a disposable wearable absorbent article can experience various loads from placement of the article on a wearer. As an example, some pretension forces from fastening the article can drive the article downward. Second, a disposable wearable absorbent article can experience various loads from the article's environment. A wearer's clothes can pull on the article, for example. Third, a disposable wearable absorbent article can experience various loads from a wearer's movements. For example, as a wearer changes positions or moves about the wearer's body can push against parts of the article or create dynamic forces in the article. Fourth, the force of gravity can move a disposable wearable absorbent article down on a wearer. The article can experience a significant load from the force of gravity, due to a mass of the article as well as a mass of any bodily waste contained in the article. These loads, can act upon a disposable wearable absorbent article, tending to move the article on a wearer.

However, other forces acting upon a disposable wearable absorbent article can tend to hold the article in place on a wearer. First, a disposable wearable absorbent article can experience various holding forces from placement of the article on a wearer. As an example, other pretension forces from fastening the article can drive the article upward. Second, parts of a disposable wearable absorbent article can experience friction forces from contact with a wearer's skin. For example, the article can experience a friction force where a waistband of the article wraps around and against the wearer's waist. Third, parts of a disposable wearable absorbent article can experience reaction forces from contact with various external anatomical features on a wearer's body. As an example, the article can experience reaction forces where the article contacts protruding portions of the wearer's hips. In this example, the reaction forces react against the force of gravity by pushing up on the article. These holding forces can act upon a disposable wearable absorbent article, tending to hold the article in place on a wearer.

As some forces tend to move a disposable wearable absorbent article down on a wearer and other forces tend to hold the article up on the wearer, part or all of the article may or may not move, depending on whether or not such forces are balanced. If the forces tending to hold the article up can equal the forces tending to move the article down, then the article can hold in place on the wearer. If the forces tending to move the article down are greater than the forces tending to hold the article up, then part or all of the article can move down on the wearer. Sometimes, forces can move down part or all of disposable wearable absorbent article, resulting in sagging and/or slipping.

However, embodiments of the present disclosure can help prevent disposable wearable absorbent articles from sagging or slipping down on a wearer. A disposable wearable absorbent article can include an anchoring system. In various embodiments, an anchoring system can be configured to collect at least some of the loads acting upon the article. The anchoring system can also be configured to anchor itself to a body of a wearer. In this way, the anchoring system can balance the collected loads with holding forces obtained from the anchoring. By balancing the collected loads with the obtained holding forces, the anchoring system can at least assist in holding the disposable wearable absorbent article in place on a wearer.

An anchoring system in a disposable wearable absorbent article can be configured in various ways to collect at least some of the loads acting upon the article. In some embodiments, an anchoring system can be configured to carry loads from an absorbent core of the article. For example, an anchoring system can include one or more elements that can be joined to the absorbent core in various ways, as described herein. In order for an anchoring system to collect loads effectively, a disposable wearable absorbent article can be configured so that the anchoring system tends to collect loads and other parts of the article tend to not collect loads. Thus, loads can be directed through the anchoring system, instead of being distributed through other parts of the article, such as the outer cover.

Parts of a disposable wearable absorbent article can be configured in various ways such that the parts tend to not collect loads. Force-decoupling can be used in some of these configurations. Throughout the present disclosure, the term “force-decoupled” refers to a configured relationship between parts of a disposable wearable absorbent article. Where a first part is force-decoupled from a second part, the parts are configured such that neither part tends to transmit a substantial force to the other, while the article is worn by a wearer. A disposable wearable absorbent article can include an absorbent core and an outer cover, wherein the outer cover can be substantially force decoupled from the absorbent core, as described in various embodiments herein.

Force-decoupling does not necessarily preclude the force-decoupled parts from being directly connected, so long as substantial force is not transmitted between the parts through that direct connection, while the article is worn by a wearer. Force transmissions from direct connections in a disposable wearable absorbent article can be substantially reduced in various ways, such as configurations of pathway lengths and/or material extensibilities. As an example embodiment, in a disposable wearable absorbent article with an absorbent core directly connected to an outer cover at a first point and directly connected to an anchoring system at a second point, the article can be configured such that a pathway from the first point through the absorbent core to the second point is shorter than a pathway from the first point through the outer cover to the second point.

The functionality of this example can be explained with the following pathway length illustration. Ends of a first rope are connected to a first point and a second point. Similarly, ends of a second rope are also connected to the first point and the second point. The two ropes are similar except that one rope is quite a bit shorter than the other. The first point and the second point are close enough to each other that the middle of each of the ropes hangs down. If the first point moves away from the second point, then the middles of both of the ropes begin to rise up from their hanging positions. However, the shorter rope will draw taut before the longer rope draws taut. The shorter rope will form a straight line between the first point and the second point while the middle of the longer rope is still hanging down somewhat. Thus, the shorter rope will carry the tension from a force that is moving the points apart. While the longer rope is still connected to the first point and the second point, it will not carry that tension.

This pathway length illustration can be used to explain the prior example embodiment with the disposable wearable absorbent article. The pathway from the first point through the absorbent core to the second point is like the shorter rope in the pathway length illustration. The pathway from the first point through the outer cover to the second point is like the longer rope in the pathway length illustration. As a result, the disposable wearable absorbent article is configured such that a load from the absorbent core causes tension through the absorbent core (shorter pathway) before it causes tension through the outer cover (longer pathway). The tension through the absorbent core can transmit through the second point to the anchoring system. Thus, in the example configuration, a load from the absorbent core can cause tension in the anchoring system before it causes tension in the outer cover.

Force transmissions from direct connections in a disposable wearable absorbent article can also be substantially reduced through configurations of material extensibilities. As an example embodiment, in a disposable wearable absorbent article with an absorbent core joined to an anchoring system and directly connected to an outer cover, the outer cover can be configured to be stretchable while the absorbent core can be configured to be non-stretchable.

The functionality of this example can be explained with the following material extensibilities illustration. Ends of an extension spring are connected to a first point and a second point. Similarly, ends of a rope are also connected to the first point and the second point. The extension spring forms a straight line between the first point and the second point, while the middle of the rope is hanging down somewhat. If the first point moves away from the second point, then the extension spring will begin to extend and the middle of the rope will begin to rise up from its hanging position. However, the rope may draw taut while the extension spring is still extending. Thus, the rope may carry more of the tension from a force that is moving the points apart. While the extension spring is still connected to the first point and the second point and extended between the points, it may carry less of that tension.

This materials extensibilities illustration can be used to explain the prior example embodiment with the disposable wearable absorbent article. The stretchable outer cover is like the extension spring in the materials extensibilities illustration. The non-stretchable absorbent core is like the rope in the materials extensibilities illustration. As a result, the disposable wearable absorbent article is configured such that a load from the absorbent core causes greater tension in the (non-stretchable) absorbent core and lesser tension in the (stretchable) outer cover. The greater tension through the absorbent core can transmit to the anchoring system. Thus, in the example configuration, a load from the absorbent core can cause greater tension in the anchoring system than in the outer cover.

In various embodiments, a first portion of an element in a disposable wearable absorbent article can be force-decoupled from a second portion of that same element. For example, an interior portion of an outer cover can be force-decoupled from an outer perimeter of that same outer cover. This can be accomplished by configuring differing material extensibilities within the outer cover. As examples, the interior portion of the outer cover can be configured with a lower extensibility and an exterior portion of the outer cover, between the interior portion and the perimeter, can be configured with a higher extensibility, or vice versa. In this way, the higher extensibility configuration in the exterior portion can force-decouple the interior portion of the outer cover from the outer perimeter of the outer cover.

As described above, an anchoring system can be configured to collect loads acting upon a disposable wearable absorbent article, to anchor itself to a body of a wearer, and to balance the collected loads with holding forces obtained from the anchoring. Throughout the present disclosure, the term “anchored” refers to a configured relationship between part or all of an anchoring system in a disposable wearable absorbent article and part or all of a body of a wearer, while the article is worn by the wearer. Where an element of an anchoring system is anchored to a portion of a body of a wearer, at least part of the element is in contact with the portion of the body and the anchoring system is configured to at least reduce and/or prevent relative movement between the element and the portion, while the article is worn by the wearer.

An anchoring system can be anchored to a body of a wearer with one or more elements of the anchoring system configured to contact various parts of a body of a wearer. For example, an anchoring system can be at least partially anchored by wrapping one or more anchoring system elements at least partway around a front, back, and/or side of a body of a wearer, thus creating friction and/or reaction forces. A part of the body with a relatively smaller radius of curvature can, in some embodiments, provide greater friction forces, since an element can tend to wrap around such parts more tightly. Also as an example, an anchoring system can be at least partially anchored by setting one or more anchoring system elements on, around, and/or above protruding portions of a body of a wearer, thus creating friction and/or reaction forces. A part of the body with a relatively larger horizontal protrusion can, in some embodiments, provide greater reaction forces, since an element can tend to hang and/or ride on such parts more securely. In various embodiments, parts of a body of wearer to which an anchoring system can be anchored, can be referred to as anchoring zones.

In order to collect loads, anchor itself to a body of a wearer, and balance various forces, an anchoring system can be configured to include a number of anchoring system elements. In some embodiments, an anchoring system element can be an elongated element configured to carry tension. Anchoring system elements can follow various pathways on external surfaces of a body of a wearer of the disposable wearable absorbent article in which the anchoring system is included. The shapes of these external surfaces can affect the shapes of the pathways. The shapes of the pathways can, in turn, affect configurations of anchoring system elements. Many external surfaces on human bodies include curved shapes, such as a curve around a hip of a human body. In some embodiments, an anchoring system element that follows a curved pathway can be a geodesic.

The term geodesic relates to a theoretical element with mathematical properties described by curved geometries. In this theoretical context, a geodesic is a curved line on a curved surface, wherein the curved line appears to travel straight, without turning to the left or to the right, when viewed from that curved surface. In other words, a geodesic can be thought of as a line pulled taut on a frictionless curved surface. On a flat surface, the shortest distance between two points is a straight line. On a curved surface, the shortest distance between two points is a geodesic. Throughout the present disclosure a geodesic with two endpoints that does not intersect itself is referred to as an “open geodesic.” Throughout the present disclosure a geodesic that intersects itself is referred to as a “closed” geodesic and the point of intersection is referred to as a “corner.”

An anchoring system element can be configured as a geodesic as the element follows various curved pathways on external surfaces of a body of a wearer. An anchoring system element that is loaded in tension (e.g., axial loading) is a geodesic, since the tension conforms the element to the curved pathway. When a point load is added to an anchoring system element that is a geodesic, at an angle other than in-line with the geodesic, that point load deforms the geodesic, creating two new geodesics in the anchoring system element. When an anchoring system element that is a geodesic is subjected to a load distributed along at least a portion of the length of the element, at an angle other than in-line with the geodesic, the element no longer behaves as a geodesic, and instead begins to act in a manner referred to herein as “geometric anchoring.”

An anchoring system can include a number of anchoring system elements, some of which can be configured as geodesics. A circumferential anchoring member (CAM) is an anchoring system element that is a physical tension carrying pathway on part or all of a closed path on a curved surface of a body of a wearer. A CAM can include a number of elements, such as anchoring bands or fasteners. Part or all of a CAM can be straight, curved, angled, segmented, or combinations of these shapes. A CAM can be made from any material suitable for carrying tensions in an anchoring system. An anchoring band is an anchoring system element that is a physical band of material with a length between two ends and a defined width that is less than the length. An anchoring band can be configured to transmit force in tension from one end to the other. In various embodiments, an anchoring band can be a load distribution element. A load distribution element (LDE) is a type of anchoring band that joins an absorbent core of a disposable wearable absorbent article to an anchoring system. One or more of these elements can be used in anchoring systems of the present disclosure, as described herein.

Throughout the present disclosure, the term “joined” refers to configurations whereby an element is directly connected to another element by affixing the element directly to the other element and to configurations whereby an element is indirectly secured to another element by affixing the element to intermediate member(s) which in turn are affixed to the other element.

The embodiments of FIGS. 1A through 17 describe various anchoring systems for use in disposable wearable absorbent articles. These anchoring systems can be configured with one or more CAMs, LDEs, anchoring bands, fasteners and/or other anchoring system elements, in various ways, as described herein. Each of these anchoring systems can be configured in a disposable wearable absorbent article to anchor an absorbent core to a wearer. In various embodiments, each of these anchoring systems can be configured in a disposable wearable absorbent article to substantially force decouple an outer cover from an absorbent core. In various embodiments, each of these anchoring systems can be configured in a disposable wearable absorbent article to carry substantially all loads from an absorbent core. In various embodiments, each of these anchoring systems can be configured in a disposable wearable absorbent article to geodesically anchor the absorbent core to a wearer. In various embodiments, a disposable wearable absorbent article can be configured with each of these anchoring systems such that a load from an absorbent core causes tension in the anchoring system before it causes tension in an outer cover. In various embodiments, a disposable wearable absorbent article can be configured with each of these anchoring systems such that an absorbent core is joined to an outer cover at a first point and is joined to an anchoring system at a second point, wherein the article is further configured such that a pathway from the first point through the absorbent core to the second point is shorter than a pathway from the first point through the outer cover to the second point. In various embodiments, a disposable wearable absorbent article can be configured with each of these anchoring systems such that a load from the absorbent core causes greater tension in the anchoring system than in the outer cover.

The second front side interface 104-2 and the second back side interface 106-2 can also be joined to form a second side interface between the front 104 and the back 106. Thus, the first and second side interfaces can each carry tension for the first CAM 130 and/or the second CAM 140 between the front 104 and the back 106.

The pant-type disposable wearable absorbent article 110-P also includes a chassis 111, leg bands 112, a waistband with a front portion of the waistband 113-F and a back portion of the waistband 113-B, a longitudinal centerline 114, and a lateral centerline 115.

The longitudinal centerline 114 and the lateral centerline 115 also provide lines of reference for referring to relative locations of parts of the pant-type disposable wearable absorbent article 110-P. When a first part is nearer to the longitudinal centerline 114 than a second part, the first part can be considered laterally inboard to the second part. Similarly, the second part can be considered laterally outboard from the first part. When a third part is nearer to the lateral centerline 115 than a fourth part, the third part can be considered longitudinally inboard to the fourth part. Similarly, the fourth part can be considered longitudinally outboard from the third part. This lateral and longitudinal terminology is used for disposable wearable absorbent articles throughout the present disclosure unless otherwise indicated.

The pant-type disposable wearable absorbent article 110-P includes the absorbent core 190 with the front portion 194 disposed in the front 104, the crotch region 195 disposed generally around the lateral centerline 115, and the back portion 196 disposed in the back 106.

However, in various embodiments, an anchoring system can be included in a pant-type disposable wearable absorbent article in a number of ways. For example, a pant-type disposable wearable absorbent article can include one or more anchoring system elements divided by side interfaces disposed further laterally inboard and/or outboard than the side interfaces in the embodiment of FIG. 1E. Also as an example, a pant-type disposable wearable absorbent article can include one or more anchoring system elements configured to extend beyond a side interface and into a corresponding front and/or back when the interfaces are joined. As an additional example, one or more anchoring system elements can be configured in side panels, which can be joined to the front and to the back on each side of a pant-type disposable wearable absorbent article. As a further example, one or anchoring system elements can be added to a pant-type disposable wearable absorbent article after side interfaces are joined, so that those anchoring system elements need not be divided by the side interfaces.

The fastenable disposable wearable absorbent article 110-F includes the front 104 and the back 106 with a first side ear 107-1 and a second side ear 107-2. The first side ear 107-1 and the second side ear 106-1 can each be fastened to the front 104 to fasten the fastenable disposable wearable absorbent article 110-F. Thus, when fastened, the first and second side ears 107-1 and 107-2 can each carry tension for the first CAM 130 and/or the second CAM 140 between the front 104 and the back 106. Such side ears can be configured to fasten to the front at locations which properly carry such tension, as will be understood by one of ordinary skill in the art. In the embodiment of FIG. 1F, the first side ear 107-1 can be configured to fasten to the front 104 at a location laterally outboard from a point at which the second end anchoring band 138 is joined to the first side element 120-1, in order to properly carry tension from the first side ear 107-1 to the second end anchoring band 138. Similarly, the second side ear 107-1 can be configured to fasten to the front 104 at a location laterally outboard from a point at which the first end anchoring band 132 is joined to the second side element 120-2, in order to properly carry tension from the second side ear 107-2 to the first end anchoring band 132.
